Be it known that l, CHARLES H. COOLEY, a spout is swung over the closer,as at the left citizen ot' the United States, residing at Harthand ofthe figure drawing, comes down ford, in the countyof Hartford and Stateof close to the closer, as there shown, and thus 55 Connecticut, haveinvented certain new and prevents the escape at that point of the grainuseful Improvements in Grain-Veighers, ot which lies in the spout and onthe closer. On which the following is a specication. the outer edge ofthe closer a xed rim 73 is This invention relates to automaticgrainprovided as a guard for preventing' overtlow Weighers, and has Aforits object to furnish imat that point, also rims, as 52 and 5i, at the6o lo proveniente in the bucket mechanism of the ends of the closer.
